Underarm Stain Removal Questions

Will this method cause the color to change on my shirt?

Anytime you use intense stain removal methods, there is a chance that you’ll lighten the color of the fabric or cause the appearance to change.

A good rule of thumb: If I’m already not going to wear the garment because of a stain, then I won’t be nervous if I ruin it in trying to get the stain out.


Can I use a detergent other than Tide?

Of course!


Should I dry the shirt in the dryer after going through this stain removal process?
